Is there a way I can test a stepper motor on my bench without the
driver? Does anyone make a stepper motor test device?
Thanks

If you take a 4 bit shift register, clock one bit around in it,

Use a meter to determine each coil resistance. They should be close.Is there a way I can test a stepper motor on my bench without the

Use a meter to determine each coil resistance. They should be close.
Then tap 5 volts across once coil, feel the shaft, it should bump once for
each tap.
The other coil should do the same thing.
Are you sure about that...Uriah wrote:

If you take a 4 bit shift register, clock one bit around in it,
connect the 3rd bit to the input,and attatch 3 bits with a 1-3
ampere darlington transistor to the 3 coils, and the common to
something like 5 or 12 volt supply, shift the register with
something like 5 hz(or use a pushbutton),
you have a nice tester.
Swap two coil wires to reverse direction.
Oh and put 1 amp diodes across the coils to keep your transistors
from breaking down.

each tap.
The other coil should do the same thing.
I was checking a few and found one coil with the resistance down from
5.3 ohms to 2.6 ohms. Is this enough to cause a problem? If one coil
is off by a few ohms this could cause the thing not to spin correctly
I would think. Because of the costs of the motor, driver pcb and down
time I hope I can find something that can tell me almost for sure that
it is good or bad. I guess I will have to experiment a little.
Thank you,

Thanks I guess this is the answer. You don't think there will be a
problem using different motors with different resistance or number of
coils?
No. Just find the common connection of the coils, and for the number
